To date I have gotten absolutely nowhere with this issue. Mr. Trabold's installation has not been approved, United helicopter has no method of approval and reports of harassment from the almighty about a ship that had one installed. Hiller,of course, is of absolute uselessness!!! This is a very simple issue!!! Why does the almighty insist on complicating it???Currently talking with DERs to try and obtain a field approval, any assistance would be appreciated.
